Contoured liner for a rectangular slotted shaped charge

A shaped charge, comprising:

• a shaped charge casing;
• a contoured liner within the shaped charge casing;
• and
• an explosive load between the contoured liner and the shaped charge casing, wherein the contoured liner includes a first wing and a second wing, wherein
• each of the first wing and the second wing includes an exterior surface that extends from a curvilinear exterior central edge to a curvilinear exterior peripheral edge,
• each of the first wing and the second wing includes an interior surface that extends from a curvilinear interior central edge to a curvilinear interior peripheral edge,
• the first wing and the second wing converge at an apex of the curvilinear exterior central edge, and
• the interior surface is separated from the exterior surface by a thickness t,
• wherein the contoured liner further includes a face surface including a first end and a second end that extends away from and is opposite the first end, wherein the face surface spans between the exterior peripheral edge and the interior peripheral edge, and
• the contoured liner further includes a curvilinear bottom edge including a first end and a second end that extends away from and is opposite of the first end, wherein the curvilinear bottom edge is defined by the curvilinear interior central edge;
• wherein at least one of the exterior peripheral edge and the interior peripheral edge of at least one of the first wing and the second wing is concave or convex with respect to a line or plan that includes the corresponding first end of the face surface and the second end of the face surface.
